Thats what challenge you have to do for pti http://nicholeheady.typepad.com today. Either use a stamp set that hasnt yet seen ink or one that has been hardly used. I have used the stamp-a-faire 1940's set which i love but have only had the chance to use once before.
I used the stamps to create the background on the card and then heat embossed the sentiment onto vellum.
The embossing powder is white with glitter so it does sparklehowever it doesnt show in the pic.
